The big Walmarts have a sporting goods section with a good range of tackle, rods, reels, rapalas, all sorts of braid, and polaroid fishing sun glasses etc.
Also VERY good quality T shirts at silly money, Also note, in Walmart if they have left an item unpriced you get it free!
A big chain called 'Sports Authority' is a must for a visit. You can buy anything from a spoole of line up to a $250000 sports cruiser ready to go. They tend to be far more professional then Walmart, with bang up to date info about who is catching what where with which rod and whatever lure and all very gung ho slap yer back fellah! Manly sportsman sorta thing. But then again you pay for it. Walmart is just a shop with loads of very well priced gear. Also where ever you go it is well worth checking out the boating/chandlery sections where you sometimes find amazing bargains like a set of 4 matched fenders with ropes for $29.99 and they can supply them deflated for you to pack, or soft leather dock shoes at $20.
Sears are a good bet too if there is one near you (The Florida Mall Kissamee ?) .
K mart is where you buy the local fishing licences (sea and fresh) and they too have very reasonable sports sections.
Good hunting.
